White Sponge for First Level Biochemical Filter Media (1M)
Fine, Wooly Type Sponge for First Level Filter Media
Sponges are part of mechanical and biological filtration and are an important step to acquiring that crystal clear water. Being larger sized, this sponge can be cut to different shapes to fit any size and form of fish tank filter you might have.
The porousness of sponges allows for beneficial bacteria to grow that helps to convert harmful ammonia to nitrates. The white sponges we recommend for first-level filtering to catch large waste particles. They work well when paired over the top of other less porous filter media.
The unique surface of a sponge makes for as much room as possible for beneficial bacteria to grow, but also leaves it prone to clogging. Because of this, sponges and other biofiltration methods are best when partnered with extra media and when cleaned regularly. Always ensure when cleaning that your biomaterial is rinsed only in your own established aquarium water though. Tap water can contain chlorine which can kill the good bacterium that has worked very hard to grow there.
Reuse and recut from the same piece for your sized aquarium and keep clean the excess in a sealed container and rinse before replacing old filter media.
